Passing a value of a variable to a symfony function

I want to render dynamicly a form in Symfony. I passing a array with elements of element names to the render method 'formElements' => array('formelement1', 'formelement2').

How i want to use the element names in my template to show the form labels.

{% for elementName in elementNames %}
    <div class="form-lable">
        {{ form_label({{ elementName }}) }}
    </div>
{% endfor %}

I received the following exception:

A hash key must be a quoted string, a number, a name, or an expression enclosed in parentheses (unexpected token "punctuation" of value "{" in onBillBundle:Customer:new.html.twig at line 17

Is it not posible to render the form dynamicly without {{ form(delete_form) }}?

Untested...

{% for elementName in elementNames %}
    <div class="form-lable">
        {{ form_label(attribute(form, elementName)) }}
    </div>
{% endfor %}

You don't need to surround variables in a twig statement with {{ and }}. So your code should be:

{{ form_label(elementName) }}

But of course elementName needs to be a Form Object and not a string. You can generate them in your Controller like this:

public function testAction()
{
    // ...
    $form = $this->createFormBuilder()
        ->add('name', 'text');

    return ['form' => $form->createView()];
}
